Be it known thatI, FRANK L. SESSIONS, aA citizen of the United States,. residing at Columbus, in the c'ountyof Franklin and State of Ohio, have invented' certain new and useful Improvements in Electric Locomotives, 'of which the following is a specification, reference beingl had therein to the accom. anying'dravving.

T iis invention relates toiin rovements'in devices by' which ,an` electric ocomotive or other vehicle can be ke t in electrical con?. nectioii with a'lixed con uctor aait moves to and from said xed conductor.

mechanism of this sort-is particularly adapted for use in electrical traction systems, suoli, for example, as are used in coal mines for gathering cars from diiierent parts of, thev 'system and also for` distributing them freni point to point, 'without the necessity of equipping the system throughout its sections or branches with an expensive electrical equipment such' as is nepessa1y-where ,the kcurrent for the locomotives is supplied-entirely through `fixed conductors.

In the drawings-Figure 1 is a side elevation, partly in*seetion, of a mechanism enibodying my improvements. Fig. .2 is a plan of the same with the coverol the vehicle re-v moved. iFig. 3 is. a'n end elevation lookin from'the yright in'liig. 1.. Fig.` 4 is' an en elevationlooking from the leftV in Fig. 1. Figs.` 5' to 16 show details.

In the drawings, I have selected, as a means of illustratingone of the ways in which my improvements can be employed, a locomotive particularly adapted for use in mines.

In an earlier patentyNo. 821,317, dated May'22, 1906, I have shownV the manner in which coal mine locomotives ol this character may be moved and guided from place to plae in the mine, and reference may be inad thereto for corresponding matters applicable to the present case.

I-Ierein, A indieatesthe locomotive as an entirety, and B the track along which it is adapted to move.

C represents the motor on thecar, and I) the winding or gathering mechanismI .by which the flexible cable .lll caribe vrou' d up or )aid out, as desired.

i is the fixed terminal or socret to which one end of the said Aflexible conductor may be connected.

, The frame` ofthe locomotiveA comprises the sideplates 1-1 and the'end plates 2f2.

4The sideplates lof the framey are out away at 3-3 to' receive the bearingblocks 4 .in which arevmounted the axles'-f These Aaxles have secured to them the track Wheels 7H7 are recesses or sockets in the plates 1. l l

8 8 aresprings seated in said sockets and side 'having 4their lower endsbearing against the bearing blocks 4 and ada ted toprovide a 'yielding support forthe rame on the said axles.` y

The motor C has its front end pivotally mounted on the axle 5', as indicated at c, c.

At its other end the said motor has a .recess C 4 l between the projections or lugs c`-, ci". i

9 is a transverse har having its ends seater in notches 10 1n the plate 1 of the traine. At.- tached-tc this transverse bar Qis a dependinff arm or bar 10 having at its lower endithe olli: vset portion 10 which 1s adapted 'to serve as a i supporting and holding arm for theaear end of t e motor C by engaging With the lugs c2 ci thereof. y thus pivotin the-motor at one end and sup orting it loose y at its other end, I provide a exibihty of mounting of the mo tor 4which `is very desirable in mechanisms of this character. Furthermore, in View of the fact tllat the axle 5 is mounted yieldingly with respect t0 the locomotive frame, the motor may also .he said to be mounted yieldin'gly relative to the said frame. The armature shaft 11' extends transversely of the frame, as shown, and is provided at one endwith the pinion 12 which is' adapted to mesh Withthe gear Wheel 13 rigidly secured to th(` axle `5. 14 is a; sprocket wheel likewise rigidly secured to the axle 5". 15 is a sprocket wheel rigidly secured tothe axle 5 iii longitudinal alineinent with the sprocket wheel'lJfA A drive chain ltloonneots taese two sprocket wheels and serves to transmit power from one to the other so that the axles 5 .'i are driven uniformly and synchronously.

17 is an arm or plate se'urod at its inner end between the be: ring blocks for tht` motor C on the axle 5. if-'1t its outer end thir plat(- 17 has hearings 17-17"inwhichther-luider shaft 18 is mounted. '19 is the pinion on oniend of said shaft adapted to mesh with the gear wheel 13. At its other end this shaft has loosely mounted upon it a sprocket 'wheel 20. A rack and pawl mechanism is interposed between this shaft and the spiocket Wheel so as,to positively rotate the` latter lil() 3D 27.27 carried by the stunflnrde ESV-28 idly Secured to the freine of the loooiuotive'et:

The positive wire e is yextended throughthe passage-wey in the shaft 26 sind with rt 'collector ring 29 secured. to the end of the eheft sind insulated therefrom. This ilisulrition of the col lm ator ring 29 is accomplished in the followiugzmanner. 3() is a wooden drum fitted into Suid collector r'iiig and rigidly secured on the said shaft 26. At the other end of the shaft 2G from the collector ring and loosely mounted thereon is a sprocket wheel 32 havits eel-tei' fece re.eeeseili ne iiifliceterl :it 33;.

to forni one element of a. friction clutch. 34 is a. chainconnecting the said sprocket Wheel 33 with the sprocket Wheel 20 on the shaft 18;

[[n order to provide e broke for the druni so thet thc speed of' its` rotation nan-be controlled iroin the operntore pletiorin, l` secure the friction plete 43 to the inuerfece of the bearing 27. When it is desroi'hto stop the rotation oi the shaft 26 the o cantor een shift the lever .2 so as to bring tlie flange 35 on the sleeve 35 'into en agement with said friction plate 43 whic i will cause .the desired result.

In an earlier :ri lic-ittico,` Serial 'No 149,667, tiled by me arch. 24, F.903,I have shown a. device for guiding the .flexible cphductoi' :is it is wound up and poid out bfy-the drum, sind reference may be mede thereto.

for en understandin of corresponding metters applicable to t e present cese, end in this application the parte will he indicated in the way followed in Seid other earlier application.' Herein, Q represents the doublethreaded Shaft, P the traveler :thereon through which the flexible cable extends, s

the slrocket Wheel on the, drum abattu-s thethe positive )lng secured to the plate 4F and adapted to -lie connected with the positive line of the current supplv system, and i7 is the negative plug secured to the plate and adapted to be connected witlrthe negative line of the current circuit. 48 is a cylindrical plu r protector made of insulating` material, pre erably wood, secured to the plate l5 and iaving the socket 48. The enlarged end 49' of the socket 49 is adapted to enter into said socket 4S. The shell of this socket 4Q which is made of insulatim material, has the passagewavs 50e-5l which lead inward from its outer end and merge into an enlarged passage-way 52, at its other end. The cable 'E is inserted into the passage-way 52 and its` )ositive and negative wires arethen separated. the 'former leading;r through the passage-way 5() to the metallic soeiiei. ot, secured in said passage and the negative wire leailiner to the metallic socket 5l secured in the passageewaj 51. 'lhese sockets are adapted to establish electrical connection between the plugs 46S-t7 and the positive and negative wires of the electrical conductor E, respectively. 'lhe parts of the plugs L1C-47 which tit into sockets 53m-54 are split, as shown, and the diameter of the plug is slightly larger than the diameter of its socket so that a tight 'fit is secured when the socket is pressed over the plug. 55 is a brush holder secured to the standard 27. This holder is insulated. from the standard, as 'indicated at 56. 57 is the brush or wiper carried by said holder and adapted to electrically contact with the collector ringl 2t). A conductor 5S leads from the binding post of the brush holder to the positive terminal of the motor.4

The course of the current is as` follows. From the positive plug 46 it flows through thepositive wire e of the flexible cable E to the collector ring 29 and then through the brush 57 to the motor. The negative terminal of the motor is electricallyT connected to the frame of the machine so that the re `turn circuit for the current 1s-throueh the frame of the machine to the shaft 2G, thence through the vflange 25 and the negative wire e to the negative terminal 47.

The gearing between the car axle and the counter-shaft which carries the reel is proportioned so as to cause the reel to ywind up the cable faster than the locomotive travels thereby insuring that the locomotive will not run over the cable. The ratchet and pawl mechanism between the axle and the Isprocket wheel Z0 is constructed to cause the rotation of the said wheel when the locomotive is runningr toward the cable or when1 windinp,l up the cable, and to permit the independent rotation of the said sprocket relative to the car axle when the cable is paid out. If the sprocket wheel 20 was secured to the shaft 18 or in other words directly connected at all times to the car axle, since the reel-is arranged to wind tip the cable fasterthan the locomotive travels, 'it would also payit oiit or unwind it with the `same linear speed which would be too rapidly for a satisfactory disposition of the cable for rewinding. f

By interosing a. friction. clutch between the drum s raft and one of the car axles and havingr one of the elements of sriitl clutch directly connected so as to rotate with said axle when the locomotive is travelingT to-r ward the unwound cable, lV insure that the `s aid elementivill be positively driven. The shifting;r `element of the clutch lV prefer to have splined to the shaft about the axis of which the other element is free to rotate and upon which shaft it is loostdy mounted, so that when the former.element is shifted in one direction it willi engage with the rotary element and cause the shaft to rotate, while when shifted a sufficient distance in the opposite direction, by enfle?,iot4 with a stationarv surface, it will operate as a brake tor the said shaft.

lt hasbcen proposed to construct a cable reeling; mechanism for electric locomotives comprising a reel shaft, a rcel secured thereon and train of power transmitting,lcvices connecting the said shaft to the motor on the car, and havingr a friction clutch in said train, one clement of which is provided by a flange on the reel drum and 'the other element of which is carried by a sprocket wheel loosely' mounted on the reel shaft and adapted to be shifted longitudinally thereof'. The shiftingr of said sprocket. wheel tends to throw the power, transmittiirg,` devices out of aline ment and to interfere with the etlicieney of the friction-al resistance between the elements of the clutch. Applicant is the ti rst to providel construction in which the cable is' positively wound, when the locomotive is running toward the cable. at a speed greater than the speed of travel of the locomotive and to automatically permit the cable to unreel at a slower speed.

The ratchet and pawl mechanism not only serves to cause the positive rotation of the reel when the loeonmtive is traveling in one direction but the engagement of the spi-ine;- held pawls with the teeth of the ratchet serve to prevent any backlashing of the cable as the locomotive runs in the opposite4 direction.
